Filed: 1970-07-15
Abstract: 1306238 Electric conductors SIEMENS AG 15 July 1970 [1 Aug 1969] 34411/70 Headings H1A and A4D A flexible region is incorporated in a superconducting cable so as to allow for contraction of the cable as the temperature falls on passage of the cooling liquid helium or cold gaseous helium. The super-conductors 21 are embedded in a tube 22 of electrically normally conducting metal, e.g. aluminium or copper, and at least part of this latter metal is removed over a part of the cable, e.g. by chemical etchants to leave the super-conductors either free from the normally conducting metal or to leave each super-conductor with an individual sheath of normally conducting metal. Copper braids 23 electrically inter-connect the two parts of the normally conducting metal 22, being clamped by clamps 24 which may also be soldered or welded to the tubes 22. The super-conductors and braids 23 in this region are bent at room temperature as shown. Coolant passes through the centres of the tubes 22 and may be contained in the flexible region by a metal or plastics corrugated extensible body 25. Within the body 25 and copper braids 23 a metal or plastics rigid tube may be slidably fitted between the ends of the tubes 22 to carry the coolant, the super-conductors being carried by slots in the tube wall, Figs. 5, 6 (not shown). The super-conductors and braids straighten out as the temperature of the cable falls. The uppermost super-conductors may be bent downwards in the flexible region so as to ensure adequate flow of coolant around them. Instead of the braids 23, laminate flexible copper conductors may be used and the super-conductors may be niobiumtitanium or niobium-zirconium alloys or multicomponent alloys based on niobium-titanium or niobium-zirconium. Short lengths of cable may be joined to produce a long cable, the joins incorporating flexible regions as described, and the cable may alternatively be enclosed in a coolanttube.

Title: Machine for treating skeins or hanks in dyeing rooms
IPC: D06B3/08
Filed: 1921-12-21
Abstract: 190,367. Mayoux, B. Dec. 21, 1921. Hank type.-A machine for treating hanks or skeins with liquids comprises a frame b, carrying hanks e in an unstretched condition on reds c, d. Eccentric straps g on the frame b rest on eccentrics n when the frame is lowered into the tank a. The frame thus receives an eccentric motion in the liquid, so that upon each rising motion the skeins, being unstretched upon the rods, are loosened from the lower reds d, and on each falling action are loosened from the upper rods c, this floating property of the skeins allowing a good circulation of liquid. The speed of movement may be adjusted to suit different materials by a stepped pulley driving the shaft of the worm screw k, and a reversing and non-continuous motion may be incorporated. A lifting-device is provided as shown but the frame b may be made separate from the beams f and eccentric straps g which would then rest permanently on the eccentrics n. The eccentrics may be replaced by cramps, cams, and the like.

Filed: 1974-08-06
Abstract: 1460994 Tone receivers; frequency-todigital conversion INTERNATIONAL STANDARD ELECTRIC CORP 6 Aug 1974 [16 Aug 1973] 34551/74 Headings H4K and H3H In a frequency tone receiver which includes a counter for counting the zero crossings of a received signal the counter is preceded by a monostable circuit which is set by the occurrence of a zero crossing of the input signal and remains set for a period which is only slightly shorter than the half cycle period of the highest frequency to be detected. A circuit ND produces a voltage spike for each zero crossing of an incoming signal, the first spike of a train setting monostable circuit MF to increment zero crossing counter NZ and setting bi-stable circuit NF to gate clock pulses to a counter TZ. Monostable circuit HF resets after a period slightly shorter than the half cycle period of the highest frequency to be detected and is again set on the occurrence of the next zero crossing to increment counter NZ. After counter NZ has counted to a predetermined number it produces an output on wire R to enable a set of AND gates U1 &c. each having a respective other input coupled to the output of a respective bi-stable device F1 &c., the inputs of which are coupled to counter TZ each to define a respective counting range Z1- Z2 representing a respective frequency to be detected. The presence of the monostable circuit renders the circuit less vulnerable to interference pulses. Reference has been directed by the Comptroller to Specification 1,221,890.

Title: Improved automatic record changing apparatus
Inventor: LANE NORMAN
IPC: G11B17/16
Filed: 1962-09-12
Abstract: 1,025,222. Automatic gramophones. B.S.R. Ltd. Sept. 11, 1963 [Sept. 12, 1962], No. 34769/62. Heading G5R. Record-diameter sensing means of an automatic gramophone comprising a selector lever which is depressed in accordance with the record diameter and adjusts the position of the pick-up arm accordingly, is characterized in that the selector lever is held in a lowered position whilst the apparatus is at rest and is released to move into its normal operative position before the lowest record of a stack on a vertical spindle is dropped on to the turntable. In Fig. 2 the selector lever 17 is free to rotate clockwise against a spring (not shown), but anti-clockwise rotation produced by the fall of a 10-inch or 12-inch record causes rotation of a cranked lever 20 and allows the end 29 of a spring-biased vertical lever 26 to rest against either the lever 20 or the fixed support part 22 respectively. With a 7-inch record the lever 17 is not moved and lever 26 remains in the position shown. The lower end of lever 26 forms a stop for abutments on a quadrant plate 36 and so adjusts the initial position of the pick-up arm. At the end of a record, an arm 39 operated by the change mechanism moves lever 26 to allow lever 17 to return to the position shown. Further movement of arm 39 causes the end 29 of lever 26 to ride up a ramp 40 on lever 20, thereby rotating lever 20 and allowing the selector lever 17 to drop. Consequently a smaller clearance is necessary between the lowermost record on the spindle and the selector lever 17. When the cycle of operation is continued, the pressure of the arm 39 is released and levers 26, 20 and 17 return to the position shown.
